If I wasn't mistaken, Parag was the only one running the whole show for TV on NAV. It is understandable things could get backed up from time to time. I have serveral emails back and forth with him during my installation and he is very helpful, even went extra miles with my own mistake during installation. I am sure that you can get frustrated when you expecting a simple return email and phone call. Just try once again and detail your question in specific, hope we all getting to happy ending.

As for the night camera quality, it is a little weak compare the OEM one that I have on my Lexus. Part of reasoning was the AGC on the camera response time seems a little slow. It take few seconds to change the iris on the lens. For most of lit parking lots, it is OK. I am thinking maybe some high power reverse light bulb might help a little. I kept the way it is so far since I don't find myself in a total dark situation that often.
